Joanna Krupa was once voted the sexiest swimsuit model in the world. And if her appearance in a bikini on Sunday is anything to go by, it’s not hard to see why. The former Dancing With The Stars contestant looked like she was enjoying herself as she celebrated her 32nd birthday in Miami. She showed off her enviable figure in a brightly coloured floral two piece, complete with a pink baseball cap and sunglasses to keep her face out of the sun.

Joanna Krupa was joined on South Beach by her sister Marta. Joanna is no stranger to flaunting her killer curves in public after she posed for the cover of Playboy magazine following her appearance on the hit dancing show in 2009. The model wowed millions of TV viewers when she paired-up with professional dancer Derek Hough. She later claimed that her appearance on the ABC TV show got her in great shape, but now admits that she rarely works out and would much rather opt for a good tan to stay looking slim and healthy.
